Curtis 1356 - Serial Port and CAN Bus Interface

Curtis 1356/1356P CAN Expansion Module Manual, Rev. A
Serial Port
e Curtis 1313/1314 programmer or the Curtis Model 840 can be connected
to the 1356 /1356P’s serial port, J2.
Power is provided through J2-4 (+12V) and J2-2 provides the I/O ground
reference.
When the 840 is connected to the serial port, it will alternately show
BDI, hour meter, and fault information.
e serial port can also be used as an external Status LED fault code display.
When the serial port is used for fault code display, a jumper must be added
between J2-1 and J2-4, and an LED is connected between J2-2 and J2-3.

CAN Bus Interface
e CAN bus interface will comply with CAN2.0B, active from 50 kbit/s to
1Mbit/s communication rate.
e 1356 /1356P will be terminated by an internal 1 kΩ resistor across
the CAN High and Low communication pins. is assumes a mid-truck con-
nection (not end-of-line).
If a 1356 /1356P without terminal resistance (models ending in -4101
or -6101) is at the end of the CAN bus, the bus needs to be terminated by
externally wiring a 120 Ω, ½ W resistor across CAN High and CAN Low.
